.SYNOPSIS...
A strong ridge of high pressure will extend over the Mid Atlantic
through the rest of the week, then slowly shift offshore toward
Bermuda over the weekend.

&&

.NEAR TERM /THROUGH TONIGHT/...
As of 945 AM Thursday...

* A Heat Advisory is in effect from 11 AM to 8 PM today.

* There is a Marginal Risk (level 1 of 5) for severe thunderstorms
  and a Marginal Risk (level 1 of 4) for excessive rainfall across
  central NC this afternoon and evening.

Clear and sunny skies to start the day will for unimpeded daytime
heating. Combined with lower/mid 70s BL dewpoints, this will support
strong and robust destabilization across the region.

Initial convective development will likely be tied to to terrain
induced differential heating and weak convergence along a lee-side
sfc trough across western NC. As storms evolve, cold-pool driven
outflow boundaries will become the primary mechanism for additional
storm development and organization.

While shear remains weak, the presence of high D-CAPE values (1200-
1700 J/KG) will foster a favorable environment for locally damaging
wind gusts with the strongest storms.

In addition to the severe storm threat, dangerous heat will persist
with afternoon heat indices climbing into the lower to mid 100s,
posing heat related risks, especially for those spending extended
time outdoors.


Previous discussion:

Lingering showers will continue to abate over the next hour or two.
Aloft, high pressure will continue ridging across the mid-Atlantic,
while a weak area of low pressure slowly drifts nwd across FL
through tonight. Weak perturbations around the low in the mid-level
flow this aft/eve could help kick off showers and storms, especially
along residual surface boundaries, with greatest coverage over the
wrn Piedmont. There should be plenty of instability, with SBCAPE
around 2500-3000 J/Kg, but relatively weak shear (less than 20 kts).
PWATs of 1.7 to 1.9 inches are also expected. An isolated strong
wind gusts and localized heavy rainfall will be the primary threats
with the storms. Convection should taper off with loss of heating.
As for temperatures, earlier convection has helped knock
temperatures down, with generally low to mid 70s across the area.
Max low-level thicknesses this evening should be slightly lower than
previous days, but still 1435-1440 meters. That and the slightly
lower starting point should result in highs near-slightly lower than
Wed, mainly in the mid 90s. However, dewpoints also in the low to
mid 70s will again result in heat index values of 100 to 106. Will
continue with the Heat Advisory, though the best chance for heat
indices of 105 or greater will be from the Triangle area east. Lows
tonight should be in the low to mid 70s, lowest west where better
coverage of convection is expected.

.SHORT TERM /FRIDAY AND FRIDAY NIGHT/...
As of 320 AM Thursday...

* Chance of storms once again, mainly across the N and W, with temps
  remaining just above normal.

The mid-upper low near the FL/GA border early Fri will continue a
NNW drift over GA through Fri night, while at the surface, weak lee
troughing holds over the Piedmont. We`ll continue to see weak
vorticity tracking through the NE side of the low over SC into W NC,
along with shots of upper divergence maxima within the southeasterly
upper jet exit region, within an area of near 2" PW. There may be
some areas of convective debris mid cloudiness and patchy low clouds
to start the day, but overall expect a period of decent heating to
facilitate convective initiation, under the influence of weak
dynamically-induced lift, particularly in areas of differential
heating. The mid level SSE flow between the GA low and anticyclone
centered off the Carolina coast will remain weak, as will the winds
throughout the column, resulting in poor bulk shear. But despite
this, with what is expected to be a period of moderate SBCAPE Fri
afternoon and decent low and mid level lapse rates across the W
Carolinas, we should see scattered (numerous in our NW) storms
develop in the afternoon, primarily slow-moving or meandering storm
clusters with the potential for strong wind gusts. Convection should
diminish gradually overnight with nocturnal low level stabilization.
Expect highs of 88-95, followed by lows in the low-mid 70s under
partly cloudy skies. -GIH

.LONG TERM /SATURDAY THROUGH THURSDAY/...
As of 240 PM Thursday...

* Hot and humid through the weekend with afternoon storm chances.

* Temperatures trend toward normal early next week with increasing
  chances of storms Tuesday and Wednesday.

Weak upper level anti-cyclonic flow will persist over head on Sunday
as the weak upper low to our southwest meanders over GA/SC. Forcing
for convection will mainly be from diurnal influences and left-over
outflow aided by moderate to strong CAPE given that the local
airmass will not change much through the weekend.  Daily highs will
be in the low to mid 90s with dewpoints in the upper 60s to mid 70s.
This results in heat indices below heat advisory criteria but still
elevated in the upper 90s and lower 100s.  Fairly climatological
POPs both days in the 25-35 ranges, with slow moving storms capable
damaging winds and locally heavy downpours with PW in the 1.5-2 inch
range.

Monday onward the mid and upper level flow becomes a little more
dominated by shortwaves crossing the northern US and the overall
pattern trends to troughing over the eastern US.  A weak cold front
is forecast to move into the OH Valley region by Tue/Wed, and while
it is uncertain if or how quickly it moves into NC, there will be
more Piedmont troughing in the afternoon and mid-level flow to move
storms over the mountains by Tue/Wed, when POPs should likely be
maximized areawide in the forecast period.  Highs will trend more
toward normal as well.

.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
As of 130 PM Thursday...

24 hour TAF period: Highest coverage of storms and associated sub-
VFR restrictions are expected across the western terminals (KINT and
KGSO) this afternoon and evening before dissipating from loss of
heating. Cannot rule out patchy ground fog at fog-prone locations
like KRWI. Otherwise, expect predominately VFR conditions through
the TAF period ending at 18z Friday.

Outlook: The best chance of storms on Friday will once again be
focused across the western terminals. Beyond that, a daily pattern
of diurnally driven convection and patchy early morning fog is
expected through early next week.
